The Psychology of Programming Interest Group (PPIG) is a collaborative community founded in 1987, dedicated to exploring the intersection of psychology and programming. This global network comprises approximately 300 professionals, including cognitive scientists, psychologists, computer scientists, software engineers, and UX researchers, all united by their interest in the cognitive and computational aspects of software development.

PPIG focuses on facilitating the rapid exchange of ideas, research outcomes, and development tools through its interactive forums and annual international workshops. The organization operates without formal membership, fostering engagement via two mailing lists dedicated to announcements and discussions.

By hosting workshops that address current topics and promoting work-in-progress discussions, PPIG cultivates an open environment for innovation and scholarly dialogue. This makes it an invaluable resource for anyone interested in delving into the psychological dimensions of programming and enhancing the understanding of human-computer interaction within various sectors.
